Google has just made available version 2.2 of its useful Google Maps for mobile application. Adding to the previously introduced public transportation for San Francisco is a new feature which lets users get transit directions all in the same place, similar to the web-based Google Maps. It has even expanded its coverage to include Chicago, Seattle, Vancouver as well as over 40 other cities across the US.

Additionally, version 2.2 lets users find the last transit trips of the day in covered cities. This comes in handy for users who rely on public transit, since they can easily schedule their activities at night. Likewise, users can also view earlier trips made by public transit. Even more useful is Google Maps for mobile’s My Location feature which lets users set the start point of their local trips.

Google Maps for mobile version 2.2 works best with Blackberry devices and other Java-based phones. In fact, it features faster searching capabilities and star rating features for business establishments.
